Hmm... I wonder if there is something similar in Photoshop.
Hey, at least you had the idea and went with it. I have yet to get the courage to play around in Photoshop like that.
There are quite a few preset 'styles' in photoshop. Depending on the version you have there should be a cartoon ish effect as a preset - just look in the style gallery - probably in the 'artistic' section.
